Internal Rate of Return (MIRR) and Profitability Index (PI). The developed model allowed for higher accuracy,
better representation and calculation of parameters based on data applicable to Trinidad and Tobago.

Environmental Impact and Risk Assessment: Data from the Technical Assessment together with literature
reviewed was used for the environmental assessment. The risk assessment was done by using an optimized
SWOT and PESTLE analysis that identified the risks of completing the project. Risk management was then
proposed for all high risk and threats that can affect the design.

Grid Impact Assessment: Calculations were done to assess the quantity of equivalent ICE vehicles that can be
removed from the nation’s roadway. The literature reviewed, data collected for the EV’s that will be present in the
Trinidad and Tobago market and recommendation from the Technical Assessment provided the required data.

Cost Benefit Analysis (CBA) is an important snapshot that is a key decisive factor for many successful projects.
The CBA included mapping of the Benefits to the Costs based on data from the feasibility study and risk
assessment. A sensitivity analysis was then performed using qualitative and quantitative analysis.

3. DATA AND ANALYSIS
The case study focused on a single fuel station at Tobago, which was Milford-24 fuel station, located at Milford
Road, Canaan. The location is ideal for analysis due to the following reasons:

• Standard fuel station design
• Data from location for research is readily available
• Harsh Environmental Conditions
• Primary source of electrical supply can be either power generation from Trinidad via submarine cable or
from Cove Power Station in Tobago.
• The island has no large scale or small scale RE projects
• Impact on Tourism
• The island of Tobago does not have any EV charging stations

SOLAR PV POTENTIAL
Trinidad and Tobago has a higher than average solar potential capable of generating between 1600-1800
kWh/kWp/yr in more than 90% of all land locations (IRENA, 2021). The information when validated was found
to be consistent with the Global Solar Atlas GSA 2.6 model.
